In case you don’t know. You didn’t provide any helpful info because kernel log is in silent mode.
Also, try to use block for your log so that others can read it more easier… really try to check your own format after sending out a comment please…
this is block
so could you please tell me how to get the kernel log ? May I ask where the official instructions are? thank you.
You can just run dmesg command in your console. There is no official instructions. It is just linux command.
I will also suggest that you remove the word “quiet” from the “/boot/extlinux/extlinux.conf” file anywhere you find it (but it will be in the “APPEND” key/value pair).
Hi, thanks. but my jetson nano was hang when it just entered the desktop. i cannot get kernel log by dmesg command. As you can see in the video, i could not do anything when entered the desktop.
Thinks, I acted on your advice. But, I still don’t have any more information from the serial port.
Is there an underlying hardware problem causing this crash, Is there any official document about checking hardware.Thinks
Sorry. Just ignore my previous comment.
Please just answer the first question here.
Are you able to interact with your board by using the serial console or not?
Sorry, I am not good at English. Thank you for any advice you give me. I relly removed “quiet” on officia baseboard B01, because Nano works normally on B01. On a baseboard of my own design, I got the above information through the serial port, but I haven’t tried to send instructions to the nano through the serial port.

Hi,
我這邊解釋一下好了… 其實有點不太理解到底困難點在哪.
首先,你能用serial console抓到log了. dmesg基本上就是在console上打幾個字然後把結果貼給我們. 移掉quiet也就是讓serial console開機的時候能順便印出kernel log. 跟dmesg上是做差不多的事情.
我知道你的困難點現在在於你的usb是不能用的狀態. 所以你應該要試著使用serial console port進行操作…
還有 custom board不能用usb port很正常, 因為原先的device tree設定是給我們devkit使用的, 如果你換了一個usb配置, 那device tree就要重改.
我不確定你對於linux kernel的device tree熟不熟悉. 如果不熟悉的話, 建議是直接找一個熟悉的人來. 不然我從頭開始講起你可能也會不太理解.
Thanks, I’m really just a beginner… I’ll try it as you say
Some basic information: Serial console has very few requirements for it to work. Other than the very simple serial UART, all of the drivers for video and keyboard exist on the host PC instead of the Jetson. That means video and USB can crash and burn and serial UARTs will continue working. In fact a very large part of the kernel can be destroyed and the serial console will continue to work. Much bootloader software is able to interact with the serial console due to this very minimal driver requirement. This means boot software would not need a video or USB driver to function with a serial console. This is one of the best (and least expensive) debug tools you can have.
I did notice an i2c error. Since this is a custom board, then you might mention if your device tree adjusted for any i2c changes. Any change in layout relative to the dev kit carrier board implies parts of the carrier board will not be found correctly if the device tree does not inform the software about those changes (and i2c is a candidate for that).
I’m extremely grateful to you and @WayneWWW. I’m just a beginner and student interested in jetson. I learned a lot with your help. Following your suggestions, I obtained the following information. As you said, I added a chip to split the HDMI signal in two, probably that’s why HDMI doesn’t work…just dp worked.I think I’ll also learn about the device tree to get to the next step. Thank you again for your help.
dmesg.txt (64.8 KB)
厄…這邊跟你建議一下. 如果你要貼log. 麻煩就做成附件.txt然後貼上來.
你這種整個複製貼上的做法對其他人而言其實不太好… 尤其是你前面已經貼了另外一份log. 我們很多時候需要用搜尋功能找一些log裡面的關鍵字的.
Thanks, Changed log to .txt file.
再提醒一下. 你的dmesg.txt每一行都被截掉了…
Note that serial console logs will show up even in boot stages. dmesg only shows up once the Linux kernel is loaded. Serial console programs run from a host PC can also log an entire session. If you have serial console running, and the logging started prior to booting, then all you have to do is boot, and then save the serial console as a log. No lines cut off, no need to copy and paste, no need to transfer the log from the Jetson to another computer (it’s already on the host PC).

Hello, thank you for your help. I just boot and save the serial console as a log.
I found this issue, thanks！
